Abstract. The newly developed system presented in this paper is based on a three-step approach and on the probabilistic assessment of independently different failure mechanisms in a slope. First, the scheme classifies rock mass parameters in one or more exposures and allowance is made for weathering and excavation disturbance. This gives values for the parameters of importance to the mechanical behaviour of a slope in an imaginary, unweathered and undisturbed 'reference' rock mass. The third… 
Stability Assessment of High and Steep Cutting Rock Slopes with the SSPC Method
The stability of high rock slopes has become a key engineering geological problem in the construction of important projects in mountainous areas. The original slope stability probability
Assessment of rock slope stability with the effects of weathering and excavation by comparing deterministic methods and slope stability probability classification (SSPC)
Cut slopes are prone to fail due to the disturbance on original geometry and strength. In addition, because of these disturbances and stress relief, natural apertures which increase the weathering
Validation of empirical rock mass classification systems for rock slopes
ABSTRACT Many classification systems have been proposed in the literature to identify the state of stability of rock slopes. Most of these classification systems involve factors relevant to the


Engineering classification of rock masses for the design of tunnel support
SummaryEngineering Classification of Rock Masses for the Design of Tunnel SupportAn analysis of some 200 tunnel case records has revealed a useful correlation between the amount and type of permanent

Weathering and especially future weathering after construction of a slope is a main cause for failure of a slopeduringitsengineering life-time. In the course of developing a rock mass classification
Rock mass classification and tunnel reinforcement selection using the q-system
This paper provides an overview of the Q-system and documents the scope of case records used in its development. A description of the rock mass classification method is given using the following six
New trends in rock slope stability analyses
Abstract The paper discusses alternative approaches to stability analyses including the traditional deterministic principle, the so-called partial factor principle and the probabilistic approach
Rock slope engineering
This book is concerned with the stability of rock slopes, with methods for assessing this stability and with techniques for improving the stability of slopes which are potentially dangerous. The
Sources of Error in Joint Surveys
Synopsis Because of the significant influence of joints on important engineering properties of hard un-weathered rock, a description of such rock is inadequate for engineering purposes unless it
